Description

Technical Field

[0001] This utility model relates to the field of boiler header technology, and in particular to a boiler header structure. Background Technology

[0002] The boiler header is an important component of the boiler. Its main function is to collect the working fluid or redistribute the working fluid to other pipelines through the header. That is, to collect, mix, and distribute the working fluid to ensure uniform distribution and heating of the working fluid.

[0003] Modern boiler headers are prone to high-frequency vibrations due to medium flow pulsation, uneven thermal expansion, or vibrations from external equipment. Long-term vibrations may lead to loose connections and fatigue cracks. Furthermore, when the bottom of the header is in direct contact with the ground, ground vibrations will be transmitted back to the header, exacerbating the vibration problem. Therefore, in order to solve the above defects, the inventors propose a boiler header structure. Utility Model Content

[0004] The main purpose of this utility model is to provide a boiler header structure that can effectively solve the problems of loose connections and fatigue cracks caused by long-term vibration in the boiler header in the prior art.

The vibration damping components include a mounting block fixedly installed on the bottom of the outer surface of the header, and a connecting plate is provided on the bottom of the mounting block. Two vibration damping springs are fixedly installed on the bottom surface of the mounting block and the top surface of the connecting plate.

[0007] A viscous damper is fixedly installed on the bottom surface of the mounting block and the top surface of the connecting plate. A support block is fixedly installed on the bottom surface of the connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model discloses a boiler header structure. By setting two vibration damping components, in actual operation, the dustproof cloth cover covers the outside of the vibration damping spring, preventing dust and debris from entering the gap of the vibration damping spring, effectively avoiding the vibration damping spring from jamming or rusting, and extending the service life of the vibration damping components.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This utility model discloses a boiler header structure, such as Figure 1-6 As shown, a boiler header 1 structure includes a header 1. The installation position of the header 1 is closely related to its function and the overall structure of the boiler. It is usually determined according to the boiler type, the arrangement of the heating surface and the working fluid flow. The working principle of the header 1 is essentially to achieve uniform heating of the heating surface tubes and efficient circulation of the working fluid through reasonable structural design and working fluid flow control. Whether it is natural circulation or forced circulation, the header 1 must ensure the stability of the "collection-distribution" process of the working fluid. At the same time, through optimization measures such as flow guidance and flow equalization, the heat load and flow resistance are balanced to ultimately maintain the safe and economical operation of the boiler. Therefore, its installation position is not limited here.

[0024] Two vibration damping components are provided on the bottom of the outer surface of the header 1. The vibration damping components include a mounting block 101 fixedly installed on the bottom of the outer surface of the header 1. A connecting plate 105 is provided on the bottom of the mounting block 101. Two vibration damping springs 102 are fixedly installed on the bottom surface of the mounting block 101 and the top surface of the connecting plate 105.

[0025] A viscous damper 104 is fixedly installed on the bottom surface of the mounting block 101 and the top surface of the connecting plate 105. The piston end of the viscous damper 104 is fixedly connected to the bottom surface of the mounting block 101. Two telescopic rods 103 are fixedly installed on the bottom surface of the mounting block 101 and the top surface of the connecting plate 105, and two damping springs 102 are respectively sleeved on the outer ends of the two telescopic rods 103.

[0026] A support block 106 is fixedly installed on the bottom surface of the connecting plate 105. The outer surface of the mounting block 101 and the outer surface of the connecting plate 105 are both provided with a dustproof cloth cover 1021. The dustproof cloth cover 1021 covers the outside of the vibration damping spring 102, preventing dust and debris from entering the gap of the vibration damping spring 102, effectively preventing the vibration damping spring 102 from jamming or rusting, and extending the service life of the vibration damping component. The outer surface of the header 1 is provided with a heat insulation sleeve 2.

[0027] When the boiler is running, ground vibration, working fluid flow pulsation, or combustion vibration are transmitted to header 1, causing vertical vibration of header 1. The vibration of header 1 is transmitted to the connecting plate 105 of the vibration damping assembly through mounting block 101. The vibration damping spring 102 undergoes elastic deformation due to compression, converting the vibration mechanical energy into elastic potential energy. The viscous damper 104 converts part of the elastic potential energy into heat energy dissipation through internal friction of silicone oil. The remaining energy is transmitted to the foundation through support block 106. Finally, the vibration amplitude of header 1 is significantly reduced, achieving the vibration reduction effect.

[0028] Multiple fixed frames 107 are fixedly installed on the side of the connecting plate 105. The fixed frame 107 has a movable hole 1071 inside, and a connecting spring 1072 is fixedly installed inside the movable hole 1071. A movable rod 1074 is slidably connected inside the movable hole 1071, and the movable rod 1074 can slide inside the movable hole 1071.

[0029] An installation head 1073 is fixedly installed at one end of the movable rod 1074 located inside the movable hole 1071, and a connecting spring 1072 is sleeved on the outer end of the movable rod 1074 and fixedly connected to the installation head 1073. A handle 1075 is fixedly installed at one end of the movable rod 1074 located outside the movable hole 1071. When the operator holds and pulls the handle 1075, the movable rod 1074 can move towards the connecting spring 1072, and then the installation head 1073 will squeeze the connecting spring 1072 and move into the movable hole 1071.

[0030] The dust cover 1021 is fixedly connected to the outer surface of the mounting block 101. Multiple fixing blocks 1022 are fixedly installed on the bottom surface of the dust cover 1021, and a fixing hole 1023 is opened on one side of the fixing block 1022. The operator holds the handle and pulls the handle 1075, so that the mounting head 1073 squeezes the connecting spring 1072 and moves into the movable hole 1071. Then, the fixing block 1022 is inserted into the fixing frame 107. The handle 1075 is released, and the squeezed connecting spring 1072 will push the mounting head 1073 to reset, so that it is inserted into the fixing hole 1023. Then one end of the dust cover 1021 can be installed with the connecting plate 105. The material of the dust cover 1021 is high temperature resistant canvas.

[0031] By separating the dust cover 1021 from one end of the connecting plate 105, the bottom end of the dust cover 1021 can be lifted to expose the internal damping spring 102 for maintenance.

[0032] The heat insulation sleeve 2 includes two heat insulation plates 201, and each of the two heat insulation plates 201 has a heat insulation layer 202 inside. The outer surface of the two heat insulation plates 201 has multiple through holes that match the outer surface of the header 1, and the size and shape of the through holes also match the various structures installed on the outer surface of the header 1.

[0033] The insulation layer 202 is made of aluminum silicate fiber cotton, and the insulation layer 201 is fixed to the inner wall of the insulation panel 201 by a high-temperature adhesive.

[0034] The two heat insulation plates 201 can be fixed to the outer surface of the header 1 by bolts. When the two heat insulation plates 201 are fixed to the outer surface of the header 1, the heat insulation layer 202 will adhere to the outer surface of the header 1, thereby improving the heat insulation effect of the outer surface of the header 1.

[0035] The working principle of this utility model is as follows: the staff first installs the header 1 in a suitable position according to the actual situation, and then the two heat insulation plates 201 are fixed to the outer surface of the header 1 with bolts, and the heat insulation layer 202 will adhere to the outer surface of the header 1.

[0036] When the boiler is running, ground vibration, working fluid flow pulsation, or combustion vibration are transmitted to header 1, causing vertical vibration of header 1. The vibration of header 1 is transmitted to the connecting plate 105 of the vibration damping assembly through mounting block 101. The vibration damping spring 102 undergoes elastic deformation due to compression, converting the vibration mechanical energy into elastic potential energy. The viscous damper 104 converts part of the elastic potential energy into heat energy dissipation through internal friction of silicone oil. The remaining energy is transmitted to the foundation through support block 106. Finally, the vibration amplitude of header 1 is significantly reduced, achieving the vibration reduction effect.

[0037] All of the above-mentioned components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0038] The specific model and specifications of components such as the damping spring 102 and damper proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method and connection method all adopt the existing technology in this field, so they will not be described in detail here.

[0039] The control method of the header 1 of this utility model is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, and the power supply is also common knowledge in the art.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
